Can anyone recommand an audio shop arround boston area?

I went to Sound In Motion, and was quoted with a high price for speaker upgrade. I understand that the speaker is Focal, but each pair of 100 KRS is 800. Plus, 800 for install into 4 door panel. IT would remain stock looking.

any other good shop arround to make it more competitive?

I know BSW has some thing.. but it was never release to E70. (Stage 1)
